Work on doc tasks that need to shift us away from deprecated features such as PlacementRule and Application Subscriptions.  This includes any interactions between AppSub used to setup the Policy Generator.

Some examples:

placementrule in use here: https://github.com/stolostron/rhacm-docs/blob/2.15_stage/gitops/gitops_policy_generator.adoc#gitops-policy-generator

General gitops should move from AppSub to Argo: https://github.com/stolostron/rhacm-docs/blob/2.15_stage/gitops/deploy_gitops.adoc#gitops-deploy-policies

Double check with Sho regarding CSO deprecation: https://github.com/stolostron/rhacm-docs/blob/2.15_stage/governance/image_vuln_policy.adoc

Ideally replace CSO with other valuable operators that integrate well with ACM Policy like cert-manager.

App Sub as the Policy Generator workflow is also described here: https://github.com/stolostron/rhacm-docs/blob/2.15_stage/governance/policy_generator.adoc
